Analysis of Impact of Selected Structure Parameters of Reinforcing Preforms for Metal-Matrix Composites on their Saturation Process

Abstract:

The process of saturation of reinforcement preforms for metal-matrix composite castings is dependent on many different factors. One group of these factors is related to the process of manufacturing of metal-matrix composites with saturated reinforcement. Another group is related to the physical properties of materials used for manufacturing of such composites. The structure of reinforcement preforms is one of such factors. Due to its complexity, its mathematical description is difficult to perform. This structure can be examined and described using physical properties like porosity or permeability. During the conducted analysis presented in the paper, it was checked whether there is a relation between studied physical properties of reinforcement preforms and a degree of their saturation. It was also determined, which of the studied parameters is the best for description of an influence of the geometrical structure of reinforcement preforms on the process of their saturation and in consequence, on the porosity of the obtained composite castings.
